You know when you look at most card or boardgames, there's an icon or set of numbers explaining how many players it's designed for? Most of the time it's 2-4 or 3-5 or whatever. Because they assume you have a group or family to play said game with. Then there are those that indicate 1-4 or 1-5 - with emphasis on "1". They're known as "Solitare" rules or in the UK, the more appropriate, "Billy No Mates".
Well, the other day I sat down and participated in such a venture! Let SADDO-CON 2011 begin! When the lady walked over and asked what I was doing and I replied in truth - the look on her face might as well have been if I were sitting there shirtless watching gay porn with another shirtless dude.
In fairness, it's a Space Hulk (because Space Hulk is super rad) card game and it plays pretty well as a solitare thing. Be fun with people as well I'd imagine. It has a neat feel and is as brutal as regular ol' Space Hulk. Though rolling dice with no one around and getting stoked is pretty fucking sad. Sadder yet was that I lost.
